NAME
     sge_qmaster - Sun Grid Engine master control daemon

SYNOPSIS
     sge_qmaster [ -help ]

DESCRIPTION
     <I>sge</I>_<I>qmaster</I> controls the overall Sun Grid Engine behavior in
     a cluster.

OPTIONS
     -help
          Prints  a listing of all options.

ENVIRONMENTAL VARIABLES
     SGE_ROOT       Specifies the location of the Sun Grid Engine
                    standard configuration files.

     SGE_CELL       If set, specifies the default Sun Grid Engine
                    cell.  To  address  a  Sun  Grid  Engine cell
                    <I>sge</I>_<I>qmaster</I>  uses  (in  the  order  of   pre-
                    cedence):

                         The name of the cell  specified  in  the
                         environment  variable SGE_CELL, if it is
                         set.

                         The  name  of  the  default  cell,  i.e.
                         default.


     SGE_DEBUG_LEVEL
                    If  set,  specifies  that  debug  information
                    should  be written to stderr. In addition the
                    level of detail in which debug information is
                    generated is defined.

     SGE_QMASTER_PORT
                    If set,  specifies  the  tcp  port  on  which
                    <B><A HREF="../htmlman8/sge_qmaster.html?pathrev=V62u5_TAG">sge_qmaster(8)</A></B> is expected to listen for com-
                    munication requests.  Most installations will
                    use  a  services  map  entry  for the service
                    "sge_qmaster" instead to define that port.

     SGE_EXECD_PORT If set,  specifies  the  tcp  port  on  which
                    <B><A HREF="../htmlman8/sge_execd.html?pathrev=V62u5_TAG">sge_execd(8)</A></B>  is  expected to listen for com-
                    munication requests.  Most installations will
                    use  a  services  map  entry  for the service
                    "sge_execd" instead to define that port.

RESTRICTIONS
     <I>sge</I>_<I>qmaster</I> is usually started from root on  the  master  or
     shadow master machines of the cluster (refer to the <I>Sun</I> <I>Grid</I>
     <I>Engine</I> <I>Installation</I> <I>and</I> <I>Administration</I> for more  information
     about the configuration of shadow master hosts).  If started
     by a normal user, a master spool directory must be  used  to
     which the user has read/write access. In this case only jobs
     being submitted by that same user are handled  correctly  by
     the system.
